BF Sort Bushing Chain for Water Therapy Drive Unit
This chain is utilised to connect water treatment gear to a energy supply. Inside the past, JIS/ ANSI variety roller chains had been utilised. For enhanced corrosion resistance, all of the parts are now produced of 13Cr stainless steel. Because the chain is operated at a slow velocity, a bushing chain with no rollers is employed. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 sorts of BF Sort Bushing Chains within a vary from 120 to 240, like heavy-duty variety.

Chains utilized for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage treatment method amenities as well as other water treatment method facilities demand particularly large resistance to corrosion and dress in considering that they may be straight exposed to sewage and sludge. A filth getting rid of chain is moved at a relatively rapid speed on an almost vertically installed rail, although the operation frequency is minimal, so WS Variety Roller Chain is used. Conversely, a chain for raking up and/or out dirt is driven at a really slow velocity and doesn’t call for rollers, so WAS Kind Bush Chain is applied.
Eighteen varieties of WS Kind and six types of WAS Style Chain can be found.
(a) WS Form Roller Chain
A WS Form Roller Chain is built to provide higher corrosion resistance and put on resistance for long services inside the extreme setting of water treatment method applications.
Because the operating time of this type of gear is comparatively quick, pins and bushings of hardened stainless steel together with other parts are manufactured of exclusive alloy steel to guarantee smooth bending from the chain, and fantastic dress in and corrosion resistance.
(b) WAS Variety Bush Chain
Heat treated stainless steel presents this chain with superb efficiency for corrosion resistance and dress in resistance.
